NASA astronaut TJ Creamer talks about his experience in space during a “Tweetup” at NASA Headquarters, Thursday, July 29, 2010, in Washington. Creamer, who spent 161 days living aboard the International Space Station as part of the Expedition 22/23 crew, set up the orbiting outpost’s live Internet connection and posted updates about the mission to his Twitter account, sending the first live tweet from orbit.

NASA mission controllers have not heard from the Mars Exploration Rover Spirit since March 22, and the rover is facing its toughest challenge yet – trying to survive the harsh Martian winter.

NASA’s Robonaut 2 has no voice but is ready to tell you its story — in 140 characters or less. The prototype robot will travel to space this fall to give NASA a deeper understanding of human-robotic interaction.

Perfectly circular, powerful Hurricane Celia spaned hundreds of miles over the Pacific Ocean in this image from June 24, 2010. Rough-textured clouds surround the storm?s distinct eye. Farther from the center of the storm, spiral arms appear thinner and smoother. The Moderate Resolution Imaging Spectroradiometer, or MODIS, on NASA?s Aqua satellite captured this true-color image of Hurricane Celia at 1:55 p.m. Pacific Daylight Time on June 24, 2010. Just five minutes later, the U.S. National Hurricane Center classified Celia as a Category 4 hurricane with sustained winds of 135 miles per hour. Image Credit: NASA

NASA selected Orbital Sciences Corp.’s, Technical Services Division in Greenbelt, Md., for the agency’s Sounding Rockets Operations contract.

Recently, technicians at NASA’s Marshall Space Flight Center in Huntsville, Ala., completed a series of cryogenic tests on six James Webb Space Telescope beryllium mirror segments at the center’s X-ray & Cryogenic Facility. During testing, the mirrors were subjected to extreme temperatures dipping to -415 degrees Fahrenheit, permitting engineers to measure in extreme detail how the shape of the mirror changes as it cools. The Webb telescope has 18 mirrors, each of which will be tested twice in the Center’s X-ray & Cryogenic Facility to ensure that the mirror will maintain its shape in a space environment — once with bare polished beryllium and then again after a thin coating of gold is applied. The cryogenic test gauges how each mirror changes temperature and shape over a range of operational temperatures in space. This helps predict how well the telescope will image infrared sources. The mirrors are designed to stay cold to allow scientists to observe the infrared light they reflect using a telescope and instruments optimized to detect this light. Warm objects give off infrared light, or heat. If the Webb telescope mirror is too warm, the faint infrared light from distant galaxies may be lost in the infrared glow of the mirror itself. Thus, the Webb telescope’s mirrors need to operate in a deep cold or cryogenic state, at around -379 degree Fahrenheit. Image Credit: NASA

NASA managers will discuss an upcoming spacewalk at the International Space Station during a news briefing at 1 p.m. CDT on Tuesday, Aug. 3.
